I am in need of some info for a newbe. I have just bought a 2003 S55 amg and the car has a couple of issues id like to know if anyone can give me dirrection. The ABC (active body controll) icon comes up on the screen every 4 or 5 times i start the car and drive. then eventually says see workshop. Is that the hydraulic Links that pressurize the front seats as you go from side to side (kinda read somthing about that) or is it the actruall stability of the car? Also does anyone have the lowdown on what Service 1 and service 2 requirements for this car are? Thanks for the info.
